The last time I lost the touchpad, the laptop was securely plugged into the wall and rebooting didn't help. After I plugged it in completely and rebooted, I got the touchpad back again. It was still getting power, because the battery wasn't draining but apparently there was something wonky about the incoming power supply. Then at another time when I noticed I'd lost the touchpad again, I checked the power supply and found that the plug was pulled partially out of the wall socket. One time when the touchpad was inoperable, I plugged the laptop directly into a wall outlet for some unknown reason and rebooted, I noticed that the touchpad was working again shortly after. I would normally have the laptop plugged into a power strip. (I'm NOT an electrical engineer so this is just a guess!) I believe the issue has something to do with the incoming voltage to the laptop. However I recently started seeing a pattern. I never knew what was causing it and in spite of trying all kinds of troubleshooting (reinstalling drivers, running various DSIM commands etc.) I could never fix it on demand and would just go back to using an external mouse until the touchpad functionality would magically return after some period of time. I have been having the exact same issue with my Toshiba Satellite S75t for a couple of years.
Now your trackpad options should correctly show up in the control panel "Mouse Options", and Windows won't replace the drivers anymore. Once it is done, restart your computer again. Now you want to unzip the Synaptics file and run the setup.exe.ĩ. If it's still there, uninstall "Asus Support Device" in device manager, under mice.
Select it and run through the troubleshooter.ħ. Again run the troubleshooter and the "Asus Support Device" should now pop up as an option. Luckily you should be able to 'disable' the driver from the troubleshooter before that happens.Ħ. This may not happen right away, sometimes it takes a while. When the computer restarts, Windows will eventually try to re-download and install the drivers. At this point you want to restart your computer. Now go into "Device Manager" and uninstall the drivers for "Asus Support Device". If "ASUS - Other hardware - Asus Support Device" isn't listed, proceed to step 4.Ĥ. If "ASUS - Other hardware - Asus Support Device" is listed, check the boxĪnd press "next" until the troubleshooter is finished. Click "Next" and then click "Hide updates."Ī. Next download this troubleshooter: https //en-us/kb/3073930ģ. Download the correct Synaptics Drivers for your system, but do not install yet.Ģ. http //support/modelHome?freeText=1200005653&osId=26 If those aren't the right ones, find your system in this section of the site and locate the drivers for it.ġ.
Without the full info on your laptop I can only go so far.
